This invention relates to improvements in winding machines andparticularly to machines for winding yarn into cops, pirns and bobbinsfor use in the shuttles of looms or packages for other purposes.

It is to be understood that the term yarn as used in the presentspecification and claims is intended to apply to all types of attenuatedmaterials, whether textile or otherwise, and the term bobbin is employedin a broad sense to mean any type of wound package.

One object of the present invention is to provide a winding machine ofthe type indicated which is of simple, compact construction havingrelatively few moving parts.

21 Claims. (Cl. 24232) Another object of the invention is to provide amachine of the type indicated in which the yarn is traversed on the copsor bobbins without the use of reciprocating elements liable to wear anddeterioration under high speed operation.

Another object of the invention is to provide a machine of the typeindicated having means for traveling the bobbins in a closed course,winding as they go, to successively bring them to a station for dottingthe completed bobbins and replacing them with fresh cores oryarn-carriers to commence winding again.

Another object of the invention is to provide a winding machine of thetype indicated comprising a rotary cam acting directly on a plurality ofyarns to traverse them on the bobbins, means for traveling the bobbinsin a closed course and means for progressively advancing the traverseduring the travel of the bobbins.

Another object of the invention is to provide a machine of the typeindicated which may be operated at high speed to increase its rate ofproduction while at the same time requiring little attention on the partof the operator except to piece up broken ends and replace the suppliesas they become exhausted.

Further objects of the improvement are set forth in the followingspecification which describe one preferred form of construction of theinvention, by way of example, as illustrated by the accompanyingdrawings. In the drawings:

Fig. 10 is an enlarged schematic view showing a development of theprofile of the cam-track or inclined raceway for shifting the windingspindles in axial direction as they travel therearound to advance thetraverse of the yarn lengthwise of the bobbins and indicating theposition of one bobbin arriving at the dofiing and donning station whereeach spindle is supplied with a fresh core or yarn-carrier.

In general, the present improved winding machine comprises a closedtrack, preferably of cylindrical form, having an inclined raceway aroundwhich the bobbins travel, winding as they go, with the cores oryarn-carriers mounted on vertical spindles which are rotatedcontinuously A traverse-cam positioned concentrically within thecircular track or raceway and rotated continuously from the machinedriving means is arranged with the plurality of yarns feeding across itshelical face to cause the strands to be traversed to a relatively shortextent. The zone of traverse is advanced progressively longitudinally ofthe bobbins to form nested conical layers producing a cylindrical bodyof yarn with tapered or conical ends. As the winding spindle travelaround the inclined circular track they are lowered pro gressively tocause the layers of yarn to advance upwardly along the cores, andeventually, as each bobbin is completed, it arrives at a station fordoifing it from its spindle and donning an empty core. The donning anddoffing operations may be performed manually but, preferably, suitableautomatically-operating means, not herein shown, are provided for thispurpose.

As herein shown, the machine is provided with eight winding spindles formounting the cores or yarn-carriers on which the bobbins are wound, butthis number is arbitrary and a greater or lesser number may be employed.The supplycops or packages are arranged above the winding spindles intwo groups supported one above the other in annular disposition about acentral standard; the supply-packages preferably being magazined withthe last delivering end from one package united to the first deliveringend of a companion supply so that the yarn will deliver continuouslyfirst from one package and then from another and the exhausted suppliesmay be replaced with full packages without arresting the windingoperation. The yarns from the supplies volve therewith within the track20. The car- .therein. Each sleeve 58 is provided with a re- "duced boreat its upper end with a bushing 59 feed through suitable tension-devicesmounted thereabove and thence lead through guide-eyes and a guiding ringto direct them downwardly to another set of guide-eyes within thetraverse-' cam and then laterally across its edge to the windingbobbins.

Referring to Figs. 1 and 2 of the drawings, the present bobbin-windingmachine'may comprise a hollow rectangular bed or. base 2 resting on thefloor or upon suitable standards, not shown, and surmounted by a hollowbox-like housing 3. As shown in Figs. 2 and 3, the housing 3 may befastened to the top wall 4 of the bed 2 by means of bolts 5 passingthrough ears 6 on the housing and screwed into threaded holes in thebase. The housing 3 encloses the driving mechanism of the machine and isprovided' on itsside with; an opening I, see j Fig'.j 3,

for permitting access thereto. The opening ,1

may be covered by a door 9 hinged to the side i of the housing 3, seeFig. l, and normally-held closed by means of a hand-latch l4 engageablewith a lug l5 on the side of the housing.

A circular opening I8 is provided in the top wall of the housing 3adjacent one end thereof, see Fig. 2. The opening I 8 is .counterboredto form a circular ledge l-9 upon which is seated the lower end of acylindrical track or raceway 20 formed with an upper cam-like rim,described later in detail. As shown in Fig. 2, the track 20 may besecured in place on the casing 3 by means of screws 21 passing throughholes in the flange surrounding the ledge I9 and screwed into threadedholes in'the sides or the track.

Fastened to the top wall l of the base 2 by means of screws 24 andextending upwardly therefrom in concentric relation to the opening l8 inthe housing 3 is a hollow column or standard 25. As shown in Fig. 2, theupper portion of the standard 25 is reduced in diameter to receive thehub 29 of a rotatable member 35, a bushing 3! being employed in thebearing between these parts to reduce wear. Themember 3!] is provided atits lower end with apair of circumferential flanges 33 and 34 which arebored at spaced intervals to provide bearing openings 35 and 36extending in parallel relation to the axis of the member. The openings35 and 36 may be provided with bushings 38 for mounting the verticalwinding spindles All of the machine, described in detail hereinafter,which are adapted 'to rotate and slide vertically therein. Fastened tothe lower flange 34 of the member 30 by means of screws 46 is aworm-gear 41 provided with teeth on its periphery, see Figs. 2 and 3.

Mounted upon the upper end of the member 30 is a rotary member orcarrie'r50 for supporting the plurality of vertical winding spindles 40,see Figs. 2 and 4, which are adapted to retherein for rotatablysupporting the upper end of a winding spindle 40. Each spindle All isprovided'with an enlarged head '4! seating upon the upper end of thebushing 59. A cup-like recess or depression 42 in each head 4! isadapted to receive the enlarged butt h of a wooden bobbin 1) forrotating the latter in the manner and for the purpose as explainedhereinafterh The lower portion of each spindle ii is journaled in thealined bushings 33 in the bores of the flanges 33 and 34 of the member35, previously referred to, and mounted on each spindle is a smallpulley 43 positioned between the flanges. As shown in Figs. 2 and 3, thespindles do are formed with relatively long keyways 45 and the pulleys43 have keys 44 engaging therein to rotatively connect them therewithwhile permitting the spindles to slide vertically in their bearings.Fastened to the side of each sleeve 58 by means of screwstZ is a key 6.3which projects outwardly through the vertical slot 56 in the side of thecylinder 55 to restrain thesleeve from rotation while permitting it toslide axially therein. A headed stud 64 having a reduced threaded shankscrewed into a tapped hole in the key 63 on each sleeve 58 carries aroller 55 journaled thereon and arranged to rest upon and roll along theupper cam-edge of the track 20, see Figs; 2 and 10.

. A rod 68 attached to the key 63 on each sleeve 58 by screws 69 extendsupwardly for mounting an 'arm l8. As shown in Figs. 2 and 5, each arm i8i formed with a split hub H which is adjustably clamped to the rod 68 bymeans of binder-screws 12. Each arm 10. terminates in a cylindrical boss73 provided with a bore 1 axially alined with its registering spindle 40and rotatable in the bore is a stub-spindle 15. As shown at the left inFig. 2, the stub-spindle 15 carries a head 16 at its lower end which isrecessed to receive the tip end of a core or wooden bobbin 1). Thestub-spindle 15 normally is urged downwardly to engage the tip end ofthe wooden bobbin b in the head'lfi by means of a helical spring llsurrounding the spindle with its ends abutting the head 15 and the underside of the boss 13. Downward movement of the stubspindle I5 is limitedby the engagement of a washer l8, fastened to its upper end by a screwI9, with the upper end of the boss 13. It will be understood from theforegoing description that the several winding cores or wooden bobbins bare held between the heads 4! of the winding spindles 40 and the headsor cups 16 on the stubspindles l5 so that when the spindles 50 arerotated through driving means, described later. the bobbins likewisewill be rotated at relatively high speed.

The yarns y are supplied to the winding bobbins from a magazine creelarranged above the winding mechanism and supported on a skeleton columnor framework comprising a plurality of v vertical rods 80 rising fromthe spindle-carrier 50. Mounted on the rods 80 are two circular shelvesor brackets 8| and 82, the upper one of which is shown in plan view inFig. 6. The bracket BI preferably is of skeleton form having spokesradiating from a central ring 83 for supporting itsouter rim which isprovided with a series of supply-holders comprising disks 84 withsuitable spindles 85 rising from the axes thereof. The supply-packages Pmay be in'the form of crosswound cones of large bulk which are seated onthe spindles 85 with their bases restin on the disks 84. As shown inFig. 6, the edge of the rim of the bracket 8| is formed with recessedguide-eyes 86 for the trailing ends of the yarns from the upper sets ofsupplies P to direct them downwardly for connection to the leading endsof the supply-packages P of the lower set.

Mounted on the upper ends of the vertical rods 80 is a circular plate81, to which are attached a plurality of tension-devices 88, equal innumber to the number of supply-packages in each series. Thetension-devices 88 may be of any usual construction; for example, of thegrid-type as shown in Fig. 1, and associated therewith are lower andupper guides 89 and 90 for directing the yarns from the supplies Pbetween the tension-grids. Supported above the plate 81 is a bracket 9|on which are mounted a series of resilient arms 92 which radiatetherefrom and carry pigtail or round thread-guides 93 at their ends. Theguides 93 are adapted to receive the yarns leading from thetension-devices 88 to direct them downwardly to a series ofPigtail-guides 94 projecting from the rim of the upper bracket 8!. Fromthe pigtails 94 the yarns are arranged to feed downwardly through agathering ring 95. The gathering ring 95 is mounted on the rods 80 bmeans of bosses 96 and is formed at its center with an axial hub 91.Held in the axial hub 91 is a depending vertical rod 38 mounting a hubor boss 99 at its lower end. The hub 99 supports a series ofradially-projecting pigtail-guide I by means of which the yarns y areadapted to be guided to the spindles 40 to wind'on the cores or woodenbobbins b. The supply-packages P of the lower series are mounted onsupply-holders similar to those previously described carried onthebracket 82 and the leading'ends of the yarns y therefrom are fastened tothe trailing ends 11 from the packages P of the upper set so that theyarns may deliver continuously first from the upper supplies and thenfrom the lower supplies, and vice versa, while exhausted supplies arebeing replaced by full packages. The complete assembly of the creel andyarn-guiding means described above is thus carried on the columncomprising the rods 00 which are supported from the spindle-carrier 50to rotate therewith as the winding bobbins b travel around the trackway20.

In winding filling bobbins for use in the shuttles of looms and for someother kinds of packages, the yarn is distributed on the cores oryarncarriers with a relativel short traverse and the zone of traverseadvanced progressively from the base to the tip end of each core. In thepresent machine the yarn is distributed on the core or wooden bobbin bwith an extent of traverse considerably less than the length of thebobbin by means of a rotary cam I05, shown in detail in Fig. '7. The camI is of dish-shape as constituted by a circular bottom wall I06 and acy-' lindrical rim I01, the upper edge of which is of helical contour'orprofile. As shown in Fig, 2, the bottom wall I 05 of the traverse-camI05 is fastened by screws I08 to a disk I09 fast on the upper end of avertical shaft I Ill. The upper end of the cam-shaft H0 is journaled ina bearing III mounted at the upper end of a tubular support H2. Thelower end of the tube H2 is fitted to the reduced upper terminal portionof the stationary standard 25. The lower end of the camshaft IIO isjournaled in a bearin II3 formed in 7 the top wall 4 of the bas 2. Thecam-shaft H0 projects downwardly below'the bearing H3 and carries astepped-face pulley II5 which is keyed thereto and held axially thereonby a set-screw III. The shaft H0 may be driven continuously by a belt II8 or by gearing connected to the main driving mechanism of the machinedescribed hereinafter.

During th winding operation the bobbins are gradually lowered withrespect to the traversecam I05 so that the zone of traverse will beshifted progressivel toward the tip of the cores b to eventually producebobbins B of the shape shown at the left in Figs. 2 and 10. This graduallowering of the bobbins is effected by revolving the spindles 40 aroundthe track 20 with the ro1.- lers 65 on the sleeves 58 riding on itsinclined raceway. Fig. 10 illustrates a development of the track 20 andindicates the manner in which the rollers 65 ride along its uppercam-shaped rim. As shown in this latter view, the upper beveled edge ofthe track 20 is formed with a short horizontal rest I and asharply-inclined portion I26 Which slopes downwardly therefrom to mergeinto a raceway I21 of lesser inclination. The raceway I2! extendsthroughout substantiall five-sevenths of the entire circumference of thetrack 20 and then merges into an upwardly-inclined portion I28 whichconnects with the rest I25. At the start of the winding operation theroller 65 for the spindle 40 of each bobbin 1) will ride off from therest I 25, travel down the sharply-inclined portion I 26 and onto thegradually inclined raceway I21, at which point the winding is commenced.As the bobbins revolvein a path concentric to the axis of the cam-shaftIIO the roller 65 on the sleeve 58 carrying the spindle 40 for eachbobbinwill ride downwardly along the raceway I21 of the track 20 tocause the bobbin to be gradually lowered whereby to advance the zoneoftraverse of the yarn upward on the core b.

The driving mechanism for the machine is enclosed in the housing 3 andmay comprise a prime-mover such as a reversible electric motor I30 shownat the right in Figs. 2 and 3. A pulley I3I on the shaft of the motorI30 may be connected to drive a vertical countershaft I22 by means of abelt I33 passing over a pulley I34 on the countershaft. The countershaftI22 is journaled in a lower bearing I35 formed in the top wall 4 of thebase 2 with its upper end supported in a bearing I36 projectinglaterally from a standard or bracket I31 bolted to the base of themachine at I38. The countershaft I22 is connected to drive the rotaryspindle-carrier 50 through a train of gearing driven from a worm I39keyed to the countershaft. The train of gearing is mounted on a bracketor standard I40 bolted to the top of the base 2 and carrying suitablebearings for the shafts of the gears. The worm I39 meshes with a gearI4I carrying a pinion I42 fast on its shaft I43 and meshing with alarger gear I44 fast on a shaft I45. The shaft I45 carries a pinion I 46meshing with a larger gear I 41 fast on a shaft I48. Keyed to the shaftI48 is a gear I49 meshing with a larger gear I50 fast on a shaft I5I.The shaft I5I carries a pinion I53 meshing with a gear I54 fast on ashaft I55. The gear I54 drives through a pair of change-gears I55 orI51, the shafts of which are mounted in an adjustable bracket I58pivoted to rock about the shaft I55. The gear I55 is mounted fast on ashaft I69 iournaled in the bracket I58 and carrying a worm I62. The wormIE2 is adapted to mesh with the worm-wheel 41, previously described asbeing fastened to the member 35 which mounts the spindle-carrier 50 forrotation therewith. l

Th change gear I51, previously mentioned, has its stud-shaft I63rotatably mounted in the bracket I58 and fast on the inner end of theshaft is a worm IE4. The shaft I55 is adjustably mounted in an arcuateslot I 65 provided in the upper end of the standard MI) in concentricrelation to the axis of the shaft I5I. The bracket I58 is also providedwith an arcuate slot I55 concentric to the axis of the shaft I55. A boltI51 extends through both slots I65 and I 65 and a nut I58 screwed ontothe threaded end of the bolt is adapted to clamp the bracket I58 indifferent positions of adjustment, see Figs. 2 and 3. With the bracketI55 in the position illustrated in Fig. '2, the gear I51 rotates as anidler during the drive through the gear I55 and worm I62 to thewormwheel 41. In other instances, however, the gear I51 maybe shiftedinto position to adapt the worm I64 fast on its shaft I63 to drive thewormwheel 51, whereupon the worm I52 will be disengaged from theworm-wheel 41. To effect this change in the drive the nut I68 on thebolt IE1 is loosened and the bracket I58 moved toward the right, asviewed in Fig. 2,'with the shaft I55 sliding in the slot I65 in thestandard I50. The bracket I58 then may be rockedupwardly to carry theworm I64 into alinement with the worm-wheel 51, after which the bracketmay be shifted toward the left to engage the worm with th teeth on theworm-wheel. With the worm I55 engaged with the worm-wheel 31 the nut IE8is tightened on the bolt I51 to clamp the bracket I58 in its adjustedposition. In this latter position of adjustment the worm-wheel 41 may berotated from the worm I65 in the same direction as that in which it isdriven by the worm I62 when the direction of rotation of thecountershaft is reversed by reversing the motor I313. The purpose ofthis arrangement is to provide that the spindle-carrier 50 will alwaysturn in the same direction even though the winding spindles are drivenin reverse direction in some nstances for the purpose hereinafterexplained.

As the spindle-carrier 55 is rotated to revolve the bobbins about itsaxis, thereby traveling them around the trackway 2B, the spindles II!are rotated by means of the pulleys 5-3 keyed to their lower ends. Thepulleys 43 are rotated by means of an endless belt I10 encircling theseries and driven by a flanged pulley I1I at the upper end of thecountershaft I22, see Figs. 2 and 3. The belt I is maintained undertension by means of an idler pulley I13 journaled at the end of an armI14 fastened to the upper end of a bushing I15 surrounding thecountershaft I22 and projecting upwardly from the bearing I36 on thestandard I31. The arm I14 has a split hub I15 surrounding the bushingI15 with a binder-screw I11 therein for clamping the arm in position tomaintain the idler pulley I13 pressing against the slack side of thebelt I10.

The traverse-cam I05 is rotated at a relatively fast rate of speedduring the travel of the winding spindles All and the cores I) mountedthereon around its circumference, the cam'being driven by its shaft H5carrying the stepped pulley II5 previously referred to. The pulley H5 isconnected by the belt II8 to a smaller pulley I69 on the lower end ofthe countershaft I22, this latter pulley having stepped faces arrangedopposite to the stepped faces on the pulley H5 so that by shifting thebelt II8 thereon the speed of rotation of the cam I05 may be varied toalter the character of the wind in accordance with different materialsbeing wound. A forked belt-shipper I within the confines of the bed 2,see Fig. 1, is pivoted to its forward side by means of a rod or shaftIBI. A handle I82 on the outer end of the shaft I8I provides aconvenient means for rocking the belt-shipper to shift the belt II8 onthe pulleys I I5 and IE3.

The complete bobbin-winding machine having been described in detail itsmethod of operation is as next explained: In preparing the machine foroperation several determining factor are first ascertained and theoperating elements adjusted in accordance with requirements. Forexample, the required number of turns or coils of yarn to be depositedon the bobbins during each traverse stroke is determined. In the presentma chine the speed of the spindles is constant and therefore to securethe correct ratio between the rotative speed of the bobbins and thetraversing rate of the yarn to produce bobbins having a definitecharacter of wind, the belt II 8 for driv in the traverse-cam I85 may beshifted on the stepped faces of the pulleys H5 and I65 in accordancewith requirements. Assuming that it is required to deposit seven coilsor turns of yarn on each bobbin during each traverse stroke in eitherdirection, the belt I I8 is positioned to pass around the pulleys H5 andI 69 in the manner shown in Fig. 2 of the drawings to provide afourteen-to-one ratio between the rotative speed of the spindle 40 andthe speed of the traversecam I55. With this latter arrangement thebobbins will be wound with what is termed a seven Wind. For producingbobbins having a five wind, as is sometimes desirable, the ratio betweenthe rotative speed of the bobbin-spindles 40 and the traverse-cam I55should be ten-to-one and to obtain this relationship the belt H8 may beshifted onto the opposite faces of the pulleys H5 and I69.

Another factor to be considered in preparing the machine for operationis whether the bobbins are to be wound with a regular or reverse wind inaccordance with the type of twist in the yarn. For producing bobbinswith a regular wind they are rotated in clockwise direction so that whenthe yarn is subsequently drawn off over the end it will unwind inclockwise direction. On the other hand, it is sometimes desirable toproduce a reverse wind by rotating the bobbins in counterclockwisedirection to provide that when the yarn is drawn off over the end itwill unwind in counterclockwise direction. With a standard threephase A.C. motor of squirrel-cage type a switch in its circuit may be used tocontrol the direction of rotation of its armature whereby to adjust themachine for producing either regular or reverse-wound bobbins. For thepurpose of illustration let it be assumed that a regular wind is desiredand that the armature of the motor I30 is rotated in counterclockwisedirection as viewed in Fig. 2, to cause the spindles 48 to rotate inclockwise direction as viewed in Fig. 8.

With the armature-shaft of the electric motor I30 rotating incounterclockwise direction and with the worm I62 in mesh with theworm-wheel in Fig. 3 whereby to slowly travel the spindles 40 in anannular course with their rollers 65 rolling on the upper face of thestationarytrack 20. At the start of a winding operation the cores orwooden bobbins b are applied to-the spindles 40 and the yarn-strands yattached thereto as they arrive at the donning station in regularsequence. The motor I30 drives the countershaft I22 and through theconnections described above -the spindles 40 will be rotated on theirown axes at relatively high speed and revolved at a slow rate about theaxis of the track 20 whilethe traversecam I05 is rotated ata speed inproper ratio with that of the spindles. Assuming that an empty spindle40 has reached the position shown at F in Fig. 10 with its rollertraveling up the-sharp incline I28 and onto the elevated rest I25 of thespindle. The head 11, of a. bare bobbin-core 1)- next may be placed inthe recess 42 of the spindle head ll to clamp the yarn between it andthe head while the tip of the core is inserted in the recess in the head70 of the stub-spindle 75 :as shown at the right in Fig. 2 and indicatedat C in Fig. 10. During this donning operation the spindle 40 will havebeen elevated by the engagement of the roller 65 on the bearing sleeve53 with the high point or rest I25 of the track 20 and thus the yarnleading from the guide 10b to the head h of the bobbin will berestrained from contact with the edge of the rotating traversecam I05.Referring to Fig. 8, during the short interval that the spindle iselevatedtoward the rest I25 on the track 20 it is displaced away fromthe driving belt I10 and therefore will not be rotated therebyl As thespindle-carrier 50 continues'to rotate slowly in counterclockwisedirection, as viewed in Fig. 8, to convey the core b to the-stationrepresented by the reference character D in Figs. 8 and 10 the roller 65will travel down the inclined portion I26 of the track 20 I and onto theless inclined raceway I21 thereof.

As the core I) approaches the position indicated at D in Fig. 10 thepulley 43 at the lower end of the spindle 40 will be carried into thepath of the driving belt I10 to be engaged and rotated thereby. As thespindle 40 and core b mounted thereon are rotated the yarn y will becaused to wind on the core and since the yarn feeds across the edge ofthe rotating traverse-cam I05 it will be traversed back andforthlengthwise of the core with an extent of traverse equal to the rise andfall of the cam-face. a

During the travel of the first bobbin from the donning positionindicated at C tothe initial winding position represented at D in Figs.8 and 10 another spindle will have been advanced to the station C toreceive a bare bobbin-core b. This core b is applied between the headsll and I6 0f the spindle 40 and stub-spindle "I5, respectively, andanother yam-strand 11 attached thereto in the manner explained above inconnection with the first bobbin considered. s the winding operationprogresses, the operator of themachine may continueto1 place emptycores 1) on the successive winding spindle 40 as the latter arrive atthe station C. During the travel of each spindle 40 from the {positionindicated at D to that represented at E their rolle s.

05 will ride down the gradual slope of the raceway I2'I on the track 20whereby to continuously lower the bobbins with respect to thetraversecam I05. Due to this progressive displacement of the cores 1)with respect to the traverse-cam I05 the zone of traverse, indicated bydash-lines in Fig. 10, will be advanced lengthwise of the cores 0 fromtheir heads h toward their tip-ends to eventually folm'filling bobbins Bsuch as that shown at the extreme left in Fig. 10.

As the winding on each bobbin i completed during its travel from theposition indicated at .U tothat represented at E the bobbin i returnedto the dofllng and donning station to arrive at station C. During theadvance of each finished bobbin B from position E to position C itsspindle 40 will be elevated as the roller 65 on its bearing sleeve 58rides up the sharply-inclined return portion I28 of the trackway 20.Duringthis upward movement of the spindle 40 a indicated at F in Fig. 10it pulley 43 will be withdrawn laterally from contact with the drivingbelt We, as shown in Fig 25 and ,8, to arrest the rotation of thespindle and bobbin and thereby discontinue the winding on this bobbin. 7

As the roller 65 for each spindle 40 rides up onto the rest I25 theoperator may sever the length of yarn leading to the bobbin, doif the11111 bobbin 5 from the spindle and replace it with an empty core '0while at the same time clamping the end of the yarn from the supplybetween the head h. of the fresh core and the head n on the spindle toprepare thi particu iar spindle forranother winding operation. it Willbe observedirom the above explanation that the present bobbin windingmachine operates continuously to travel the bobbins in an annularcourseduring the winding operation and to advance them individually intoposition for coiling and replacement by fresh cores 0. 'While for thepurpose of the present disclosure the doirlng and, donning operationshave been explained as being performed manually, it is contemplated thatautomatically-operated means be provided for effecting these functions;but since such mechanism forms no part of the present'inven tion it isnot herein shown or described.

During the winding operation the central column or standard comprisingthe vertical rod 80 is rotated slowly with the spindle-carrier 50 towhich the rods are attached so that the supplypackages P mounted. at theupper end of the column will revolvetherewith. 7 When the supply of.yarn inflone package P is exhausted the connected strand deliveringfrom anew package arranged below. or above as the case may be,.will feeddownwardly to the bobbin B being wound. A fresh supply-package P thenmay be substituted. for the empty cone-tube or other yarn-carrier andthe leading end of its strand tied to the trailing end of the yarn inthe package from which the yarn is delivering. In this manner thesupply'of yarn is maintained continuous with the result that the windingoperation may proceed without interruption.

When it is desired to produce bobbins having angina in the directionindicated by the arrows in Fig. 9. To efiect thi reverse rotation of thespindles 49 the switch of the electric-motor l-3il may be shifted toreverse the direction of rotation of its armature shaft and pulley 13!.Referring to Fig. 9, when the bobbins b are rotated in counterclockwisedirection the yarn-strands will be wound thereon in the same directionso as to draw off over the ends thereof in counterclockwise direction asis sometimes desired. Thi is especially desirable when certain kinds ofyarns are to be used for Weaving since it is possible to obtain a'moreuniform tension with less kinking ofthe yarn as thelatter delivers fromthe shuttle.

Regardless of the direction of rotation of the spindles t9 during thewinding operation, the

spindle-carrier 55 must always rotate in counterclockwise direction, asviewed in Fig. 4, to insure thatthe rollers 65 will travel in the properdirectionon the track 20. When'the direction of rotation of thecountershaft is to be reversed the nut 58 on'the bolt It! is loosenedand the bracket 53 rocked about the shafts l5! and I55 to mesh the worm164 with theworm-wheel 41 on the spindle-carrier 59, after which the nutis tightened to hold the bracket in adjusted position. With the variousparts adjusted in this manner the gear I 56 will be driven in theopposite direction from that first described to drive it companion gear[51 in reversedirection and turn the worm I64 to rotate the carrier 50in counterclockwise direction to effect proper co operation between therollers 65 and track 20.

Referringto Fig. 10, the sloping raceway I21 of the track 20 maybeformed with a profile. of greater or lesser inclination for different.lengths of bobbins or its cam-face maybe variedin other ways as requiredfor different types of packages, all within the scope and purview of thepresent. invention. For example, to wind bobbins having parallel-sidedcylindrical .body portions .on ta- It will be observed-from theforegoing speciflcation that the present inventionprovides abobbin-windingmaohine which is of simple, compact construction Whilebeing highlyefflcient. inoporation. It also will beobserved that inv thepresent machine comprising a plurality of winding spindles arranged totravel about the centrally-located cam, common to all the spindles, thetraversing means is reduced to utmost simplicity, thereby eliminatingthe. usual reciprocating yarn-guides and other parts liable to. wear anddeterioration in use. It will be observed further that the meansforadvancingthe traverse of the yarn lengthwise of the bobbins is common toall of the several winding spindles and avoids the use of screw-threadedprogression wheels, ratchet-devices and other complicated mechanisms.Thus, the present improved machine provides for winding a plurality ofbobbins continuously at high speed by the use of extremely simplemechanism while requiring little attention on the-part of the operator.7
